Ryan Martin’s Indiana Ag Forecast for December 10, 2018

We remain dry for the next few days, but still have two waves of moisture coming for the second half of the week. There are no dramatic changes to our forecast this morning as we start off a new week, but we are tweaking timing of our next 2 systems just a bit.

Dry today, tomorrow and most of Wednesday. Sunshine will dominate today and tomorrow, but we will start to see clouds increase through the day Wednesday. Temps will stay cold for the next couple of days as west winds dominate over the state. South winds start to develop Wednesday night.

Light precipitation noses into the state from the west Wednesday evening and then continues through Wednesday night. By sunrise Thursday, everything is already done. Moisture totals will be a few hundredths to .2” with coverage at 70% of the state. This round of precipitation will be predominately snow, and we can see a fresh coating to an inch or two, but generally we stay under an inch and closer to flurries. Rain can try and mix in over far southern Indiana, but we may end up with mostly light snow.

We are dry for the balance of Thursday and Thursday night. A second wave of action works in for Friday. This wave comes up from the southwest again. From I-70 southward, we are looking for .25”-.75” of liquid equivalent precipitation, while north of I-70 we only see some spotty showers. Temps should be warming for late this week too, which will allow for at least half, if not all of our precipitation to come as light rain, or at least a light rain and snow mix. That wave exits quickly as well, giving us some clearing overnight Saturday night.

We should be dry for Sunday. Overnight Sunday night into Monday we have a front that sweeps across the state and that should allow for some colder air. AT least we have some cloud cover that develops, and at worst, we could see a few hundredths of an inch to .1” of moisture trying not come in for Monday as either a rain-snow mix, or predominantly rain. The best moisture will be over the southern third of the state.

Dry next Tuesday and Wednesday to close out the 10-day weather window. In the extended, period we start with a chance of rain from late the 19th into the 20th, .1”-.6” rain totals (yes, rain again). Then we have some snow coming to about 70% of the state for the 22nd and 23rd with potential up to a few inches. But then we go drier but remain cold for Christmas Eve and Christmas Day.
